Check to see if the battery needs replaing or if someone cut or pushed the wire that hangs down about 6in on the back of the opener.

The key pad will close the garage door but it will not open the garage door.

If the keypad is the only remote unit you have that has short range then it is failing. The lack of signal strength prevents the signal from reaching the receiver when the door is closed. A replacement is the only cure.

How do I uninstall my garage door sensors. They continue to give me problems, it acts like there is something in front of the sensor and prevents the door from closing.

When you say sensors, are you talking about the photo-eye that checks if obstruction is in path of garage door?

1) You can buy sensors for $20-30. They seem generic

2) The new openers may be set up so by-pass is not an option.
Solution: In that case, you can move sensors above the garage door and put them face to face to see if that helps.

3) The way the sensors work is this. One side produces beam of light. Other side receives light. The receiver keeps a circuit closed at all times when light is received. If no light, then the circuit opens up and an electronic part interprets the lack of signal and turns off opener.

Solution: one side produces light. It does not have a switch. The other side has the switch. You can disconnect (or cut) a wire see which side has the light. The other side has the switch ... cut the 2 wires on the side with a switch, cap them off, and then see if opener works. Next twist the 2 wires together and see if opener works.

4) Fall-back position: Mark your wires and you can put it back the way it was.

My garage door opener from sears will not close the door from the outside. i have to go back in the house, close it with the button on the wall, then go back out. It does, however open the door when I...

If when you try to close the door with the remote it starts down and then the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. Each of the sensors has a small light that should be lit and not flickering. Tweak the sensors a bit. If you cannot get both lights to come on you have bad sensors.

It sure sounds like you have a light bulb that is generating a radio signal that interferes with the receiver in that one opener. Remove the bulbs and try. As strange as it sounds it can happen.

Garage Master 1/3 HP 1997 Door Working, not responding to Remote

I have the exact same situation, except my model (139.53607) is older than yours and does not even have an LED. Remotes only works after after shop light goes off (5 minutes or so), but wall button works fine. Did call Sears Service and the tech told me the logic board is probably shot. Don't want to waste money on service call so I'll probably have to buy a completely new unit in the Spring and go through the winter without the use of a remote.

Automatic Garage door reverses and automatically opens after closing

I can't believe it! My opener works fine a 10 degrees and above but below 10 degrees it would go down a little ways stop and go back with the light flashing. I checked the electric eye and found it would go out of alignment when the temp drop. Who knew!
I made the adjustment and it now works fine.
